Choose a pace that feels easy
The controls allow 2–8 seconds in and 2–10 seconds out, without breath holds. The paper lantern grows and brightens during the inhale, then softens during the exhale. Follow your own comfort; the lamp is a visual rhythm, not a prescribed exercise or medical treatment.
Time follows the clock
Phases are calculated from elapsed timestamps rather than a number of rendered frames. Pause preserves the current position; reset returns to the beginning. Changing the pace pauses and resets the rhythm. The page pauses automatically when hidden, and it resumes only with another click.
The lamp can stay still
Reduced-motion preferences keep the lantern still while phase and remaining seconds appear as text. You can also choose this mode manually. Saving creates a still artwork with the current pace settings; it does not certify practice, count completed sessions or promise an effect.
